Stereo, mono, 5 channels, a zillion channels, it's all an illusion. There is no way to recreate a concert hall, or club performance at home. And studio recordings are another can of worms, which for the most part, have completely artificial acoustics and arbitrary placement of performers in a contrived 'soundstage.'
The question is: How is the illusion created? Provided that a recording has captured all the necessary auditory cues, it's going to take more than two channels to accurately deliver all those cues to our ears.
